899 Corbett Ave, San Francisco, CA 94131

The three-story, three-unit multi-family residential building at 899 Corbett Avenue in Twin Peaks, currently owned by Richard Ruhland Revocable L, has undergone several significant maintenance and improvement projects since its construction in 1960. Recent work includes a completed reroofing project in 2017 costing $21,800, and critical infrastructure updates such as a sewer lateral replacement with new house trap in 2016.

The building has a history of moisture-related issues, with multiple complaints about water damage and leaks between 2004-2006, including a significant incident in 2004 involving ceiling leaks and mold. The property underwent several system improvements, including an electrical PG&E underground conversion in 2004, and attempted furnace and duct upgrades in 2015, though this permit expired. The building experienced notable maintenance challenges earlier in its history, with multiple violations documented in 2004-2005 related to interior surfaces, including water-damaged ceilings and walls, weatherproofing issues, and kitchen appliance problems, all of which were abated by April 2004.

More recent concerns include a sleeping area requirement violation issued in November 2023, though this was subsequently rescinded. The property has maintained an active status with routine housing inspections, with the most recent complaints in late 2024 primarily related to exterior issues such as graffiti and public works matters, rather than building systems or tenant conditions. The building's maintenance history shows a pattern of addressing both cosmetic and structural issues over time, with periodic upgrades to essential systems and prompt response to violation notices.
